This adds support to the softpipe texture sampler and tgsi exec.
In order to handle the extra input to the texture sampling,
I've had to expand the interfaces to take a c1 value for storing
the texture compare value for the TEX2 case.

This just adds the texture target and capability along
with 3 new opcodes required to support this extension.
As this extension requires some texture opcodes with samp + 5 args,
we need to use another src register, this is only required
for TEX, TXL and TXB opcodes to implement this spec.
TEX2 is required for shadow cube map arrays
TXL2 is required for cube map array sampler + explicit lod
TXB2 is required for cube map array sampler + lod bias

While developing cube map array support I found that we didn't
support this properly, also piglit didn't test for it at all.
I've submitted a test to piglit to check for this, and this
fixes explicit lod and lod bias with cube maps.
NOTE: This is a candidate for the 9.0 branch.

For cube map arrays I'll need another driver private constant
buffer, and looking forward to UBOs. So clean up with some
defines, that can be modified when adding cube map array and ubos
later.

If a frame callback is not destroyed when destroying a surface, its
handler function will be invoked if the surface was destroyed after the
callback was requested but before it was invoked, causing a write on
free:ed memory.
This can happen if eglDestroySurface() is called shortly after
eglSwapBuffers().
Note: This is a candidate for stable branches.

The decompression is done in-place and only the compressed tiles are
decompressed. Note: R6xx-R7xx can do that only with Z16 and Z32F.
The texture unit is programmed to use non-displayable tiling and depth
ordering of samples, so that it can fetch the texture in the native DB format.
The latest version of the libdrm surface allocator is required for stencil
texturing to work. The old one didn't create the mipmap tree correctly.
We need a separate mipmap tree for stencil, because the stencil mipmap
offsets are not really depth offsets/4.
There are still some known bugs, but this should save some memory and it also
improves performance a little bit in Lightsmark (especially with low
resolutions; tested with Radeon HD 5000).
The DB->CB copy is still used for transfers.

The problem was we set VRAM|GTT for relocations of STATIC resources.
Setting just VRAM increases the framerate 4 times on my machine.

On r6xx/r7xx shader resource management need to make sure that the
shader does not goes over the gpr register limit. Each specific
asic has a maxmimum register that can be split btw shader stage.
For each stage the shader must not use more register than the
limit programmed.

v2: update relnotes-9.1
v3: use align_malloc and align_free for malloced buffers in r300g
v4: document the new CAP in the docs
This allows updating only a subrange of buffer bindings.
set_vertex_buffers(pipe, start_slot, count, NULL) unbinds buffers in that
range. Binding NULL resources unbinds buffers too (both buffer and user_buffer
must be NULL).
The meta ops are adapted to only save, change, and restore the single slot
they use. The cso_context can save and restore only one vertex buffer slot.
The clients can query which one it is using cso_get_aux_vertex_buffer_slot.
It's currently set to 0. (the Draw module breaks if it's set to non-zero)
It should decrease the CPU overhead when using a lot of meta ops, but
the drivers must be able to treat each vertex buffer slot as a separate
state (only r600g does so at the moment).
I can imagine this also being useful for optimizing some OpenGL use cases.

The 2x and 4x MSAA cases are completely broken. The lfdptr instruction returns
garbage there.
The 8x MSAA case is broken on Cayman, though at least the result looks somewhat
correct.
Only the 8x MSAA case works on Evergreen and is enabled.
We're starting to get apps utilizing more than 16 varyings and
most current hardware supports 32 anyway.
Tested with r600g.
swrast, softpipe and llvmpipe still advertise 16 varyings.

So I restrict assiging of lvm::StackAlignmentOverride and other
